HINGE.

Specification of Letters Patent.

Patented Jan. to, 1915.

Application filed June 10, 1914. Sdrial No. 844,342.

To all whom it may concern Be it known that 1, CHARLES WILLIAM CARTER, a citizen of the United States, residing at Fairfield, in the county of Hyde and State of North Carolina, have invented certain new and useful Improvements in Hinges, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to hinges, and more particularly to door hinges and has for its primary object the provision of a hinge of this character which will effectually serve to permit the door to positively remain in any desired opened position adjustment.

Another object of the invention is the provision of a hinge structure in which the several parts thereof may be connected with each other expeditiously during the manufacture of the article, while arranged relatively under normal condition whereby the leaves can be freely separated from each other as the occasion may demand.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be hereinafter de scribed and claimed.

In the accompanying drawings :Figure 1 is a side view of the hinge; Fig. 2 is a similar View, showing parts in section; Fig. 3 is a section on the line 33 of Fig. 2; Fig. 1 is a section on line H of Fig. 2.

The hinge comprises companion leaves 1 and 2 provided with alined knuckles 3 which are substantially of the usual formation, except the knuckles 3 of the leaf 2 which, as illustrated are respectively provided with longitudinally alined bosses 1 and 5, the former being provided with a circular series of substantially ratchet teeth 6 of V-shaped formation in transverse section.

The pivot pin or pintle 7 freely passes through the knuckles 3 of the leaves 1 and 2 and at the upper end said pin is provided with a head 8 whose under surface is provided with an annular series of teeth 9 of V- shaped formation in transverse section. These teeth are adapted to cooperate with the teeth 6 upon the boss 4:, and they are normally held in engagement therewith under the influence of a spring 10.

The boss 5 of the leaf 2 is provided with a recess 11, in which one end of the spring 10 is seated. The pintle or pin 7 has its lower end extended to a point below the lugs 5 and it is threaded for a short distance in its length, as at 12, to accommodate a hollow nut or cap 13 having cylindrical walls 14 which embrace the walls of the lugs 5. The cap 13 freely receives the lower end of the spring thereagainst and through this arrangement it is evident that the teeth of the head 5 will be normally held yieldingly engaged with the teeth 6 of the boss 1. The cap 13 may be freely removed from the pin 7 and the latter can then be freely withdrawn from the knuckles 3 of the leaves 1 and 2 so as to permit said leaves to be readily separated from each other.

The knuckle 3 of the leaf 1 is provided with a longitudinal slot 16 in which a pin 17 upon the pin 7 extends and by associating said pin 17 in the slot 16 as just mentioned, it is apparent that the pin 7 will be properly held against rotation at the time that one of the leaves of the hinge is turned upon the other. Also, through this arrangement the pin 7 is free for vertical movement to permit the teeth 9 of the head 8 to freely pass over the teeth 6 of the boss a when the hinge leaves are moved angularly of each other. Through the arrangement of the parts generally it is also apparent that one of the leaves may be held at any desired angle with relation to the next adjacent leaf of the hinge. This is desirable in order that the door to which the hinge is connected may be readily and in fact automatically retained at any point in its adjustment.

What is claimed is:

1. A hinge comprising a pair of leaves, having alined knuckles, .a toothed boss formed on one leaf, a pin passing through the knuckles of both leaves and having a toothed head overlying said toothed boss, means for yieldingly holding the teeth of said head engaged with the teeth of said boss, and means for preventing rotation of said pin with relation to one of said knuckles.

2. A hinge comprising a pair of leaves, one of the leaves having spaced knuckles at its ends, the other of said leaves having a knuckle intermediate of its ends adapted for alinement with the first mentioned knuckles, a toothed boss on one of said end knuckles, a pin passing through the knuckles of both leaves and having a toothed head on one end overlying said toothed boss, means for preventing rotation of said pin with relation to said intermediate knuckle, the other end knuckle having a recessed boss, a hollow cap mounted on the other end of said pin to sur round said recessed boss, and a spring disposed Within said recessed boss and said cap to yieldingly hold the teeth of the head engaged With the teeth of the boss.

3. A hinge comprising tWo leaves having alined knuckles, a toothed boss on one leaf, a pin passing through the knuckles of both leaves and having a toothed head overlying said boss, the pin being free for sliding movement in the knuckles, means yieldingly holding the teeth of the head engaged with the teeth of said boss, the knuckle of one leaf having a longitudinal slot therein, and 15 means on the pin passing through said slot, as and for the purpose specified.

In testimony whereof I hereunto afiiX my signature in the presence of tWo Witnesses.
